METHOD OF MAKlilG ORNAMENTED ARTICLES OF SOFT SHEET METAL.

Application tiled March 8, 1553.

.50 (til whom, it may concern.-

Be it known that I, J. ALVIN EAIDES, of Middletown, in the county ofMiddlesex and State of Connecticut, have invented certain new and usefulImprovements in Making Ornamented Articles of Soft Sheet Metal; and Il.do hereby declare that the following is a full, clear, and exactdescription thereof, whereby a person skilled in the art can make anduse the same, reference being had to the accompanying drawings, and tothe letters of reference marked thereon.

Like letters in the figures indicate the same parts.

My improvement relates to articles made of soft sheet metal havingcomplicated or irregir lar formssuch as napkin-rings, tableeasters,pitchers, tea-pots, and thelike, which, among other designs are verycommonly provided with ornamental bands around them alternat ing withplain metal surfacesand to new methods of manufacturing the same, ofwhich the following is a description, retercnee being had to theaccompanying drawingf-i, in which I have represented a napkin-ring and asmall cup as being the simplest articles with which to illustratemyinvention.

Figure 1 shows an end and side view of a cylinder of metakwhich may becalled a napkin-ring blankfl 'the side view, a, showing theornamentation applied to the blank before spinnin Fig. 2 is a side viewof the napkinring spun into shape after the ornan'icntation has beenapplied to the cylinder or blank, having the exterior ornamental bandsin allerlhg. 3 is a view of a ring of similar form shown in longitudinal section as made up by the old method in separate sections, thesoldered joints being shown in heavy transverse lines. Fig. a representsa Hat disk of metal ornamented upon one side before being spun. 'Fi g. 5represents a cup spun into shape from such an orna niented disk. Fig. 6represents the body of a tea or coffee pot spun from a straight tube orcylinder after three ornamental bands have been imprinted upon it, thethree bands being made by the use of thcsame ornamcntingroll.

Articles of this class have been heretofore l lo. 309,531, Beeember 23,188%.-

made of separate rings or parts, some of such par '2; being rolled withan ornamental pattern, and some plain, all of which have been separatelyformed to their required shape and then soldered together to form thecomplete article; and also in some instances the bands, after beingornamented, have been soldered upon the outside of the plain surfaces ofarticles. The rolling of an ornamental band elongatcs or stretches themetal, and for this reason such parts have been made separate, so thatwhen bent round and the ends united by soldering it should unite withand be of the same size as the adjacent plain portions; also the properform has been given to these ornamental bands by driving them onto ablock or former of the desired sectional shape, in order not lo injurethe figures of the design, while the plain portions of the article havebeen spun into shape. This method of making such articles by uniting thebands of plain and ornamental work after their shapchas been given tothem is a very laborious process, and requires skilled workmen, and eventhen the united joints are not always true and perfect.

The object of my invention is to make a much more perfect article byspinning the bodies into shape from one piece 01" metal after theornamentation has been applied thereto.

1 have discovered that the ornamentation can be rolled or otherwiseimprinted upon a sheet or disk of plain metal so as to cover only aportion of its surface, or that such ornamentation can be rolled orotherwise made upon a portion only of atubular or cylindrical surface,and the whole then spun into any shape desired in substantially the samemanner as plain metal.

In the accompanying drawings, a, Fig. 1, is an end view of a cylinder ornapkiirring blank. a is aside view of such blank, show;

ing ornamental bands applied thereto.

Z) denotes the ornamental bands, and c the plain bands, in each of thefigures.

d, Fig. 3, denotes the joints where the several bands are solderedtogether when the ar ticles are made by the old method.

of g, Figs-4t and 5, respectively, denote the same ornamentation on thedisk before spinning, and on the cup spun therefrom, and p theunornamented portions.

h i 70, Fig. 6, are ornamental bands on dif ferent portions of a tea-potbody illustrating the change produced by the spinning operation uponfigures originally imprinted upon a straight cylinder by the sameornamentingroller.

In my improved method of mai'iufacture, when an ornamental band isrolled upon a plain surface, the metal being held from elon gating bythe plain metal upon each side, it bulges upward and becomes somewhatdistorted but this can be readily rolled or pressed down, so as topresent a flat surface again. The whole can then be spun into the shapedesired according to the usual method. For this purpose I use a woodentool, and fill the ornamental designs with soap, so that the pat ternshall not be injured or disfigured during the spinning operation.

By means of my improved method of ornamenting plane or cylindricalsurfaces of soft sheet metal, and afterward spinning the metal into theform of the ring, cup, tea-pot, or other article desired, I am enabledto pro duce a great variety of different forms of fig ures upon thefinished articles by the use of only a few different designs upon theorna- 1nenting-rolls. For instance, by imprinting several ornamentalbands with the same roller upon different portions of a plain cylinderor tube, and afterward spinning the cylinder into the form of a tea-pothaving alternating swelled or bulged and contracted portions throughoutits height, shown in Fig. 6, the spinning operation will in someportions of the article lengthen out the ornamental figures and contracttheir width, as at t, Fig. 6, while in other portions of the article thefigures will be expanded in width and contracted in length, as at 7 Fig.6, which gives the finished article the appearance of having beenornamented by a variety of rolls with a different figure out upon each;and also by means of my improvement articles which have heretofore beenmade in several parts can be made of a single piece and present a muchmore finished appearance than is now possible, at the same timedispensing with the clumsy and heavy, as well as unsightly,solderedjoints, and leaving the articles smooth and uniform in all theirparts.

In the manufacture of deep hollow vcsselssuch as pitchers, coffee andtea pots, &c .-it will be found more advantageous to first spin frustaof cones with one end closed, then to apply the ornamentation, andafterward to spin these cylinders into the requisite shape; but whenmaking shallow articlessuch as cake-baskets, cups, caster-bands, &c.theornamentation may be applied to the fiat disks of metal, which afterwardare spun into the shape desired.

The ornamentation may be applied to the sheets or cylinders of metal byany of the wellknown means; but I have found the most ecothereon thecounterpart of the design upon the periphery of the rolls.

The method of producing ornamental designs on sheet-metal articlessuggested in the English provisional specification of Thomas WVhite, No.1,757, of the year 1879, I have found upon trial to be whollyimpracticable, for the reason that composite sheets of metal produced bysoldering cannot be fashioned into articles by spinning, because thisoperation tears apart the separate pieces of metal united by solder. Onthe other hand my method is practiced by the employment of homogeneoussheets of comparative] soft metal, and the operation of soldering iswholly dispensed with in the article so fashioned.

What I claim is 1. The art or process of making ornamented hollowarticles with the bodies formed from a single piece of sheet metalwithout soldering by, first, ornamenting the surface ofa plain cylinderor other tubular form of metal, and, second, spinning such ornamentedcylinder into the shape desired forthe articleto be produced,substantially as described.

2. The art or process of making ornamented hollow ware from one piece ofsheet metal by, first, ornamenting the surface of a disk of metal, and,second, spinning such ornamented disk into the shape of the articledesired, substantially in the manner described.

The art or process -of making soft sheetmetal hollow ware withornamented homogeneous bodies complete without soldering by ornamentingthe metal before final shaping, and subsequently spinning it into theultimate shape of the article desired, substantially as described.
